Is there a name for this type of crime show?

There seem to be a bunch of series out there that have a police department investigating crimes - often times, murders - with help from an unexpected source, an outside contractor. Some examples:

In Bones, you have a forensic anthropologist (okay, that's not that unexpected a source).
In Castle, it's a writer. (If I'm correct - I haven't seen this one yet.)
In Intelligence, it's a guy with access to the information network with a chip in his brain.
In Medium, it's a medium.
In Numb3rs, it's a mathematician.
In Perception, it's a hallucinating neuroscientist professor.
In Unforgettable, it's a person with something like photographic memory.

I was wondering if there was some name by which to refer collectively to shows of this type. I find them interesting, and would like to find other, similar shows.

Thanks in advance.
